What is claimed is:

1. An apparatus comprising:

a memory array; and

a controller to:

receive a first read command specifying a read voltage offset profile identifier; identify a read voltage offset profile associated with the read voltage offset profile identifier, the read voltage offset profile comprising at least one read voltage offset; and

perform a first read operation specified by the first read command using at least one read voltage adjusted according to the at least one read voltage offset of the read voltage offset profile.

2. The apparatus of Claim 1, wherein the read voltage offset profile identifier is specified in an address cycle of the read command.

3. The apparatus of Claim 1, wherein the controller is to:

receive a second read command specifying a default read voltage offset profile identifier in an address cycle of the read command; and

determine not to adjust the at least one read voltage based on the default read voltage offset profile identifier for a second read operation.

4. The apparatus of Claim 1, wherein the read voltage offset profile identifier is specified in a last address cycle of the read command.

5. The apparatus of Claim 1, wherein the read voltage offset profile identifier is specified in a command cycle of the first read command.

6. The apparatus of Claim 1, wherein the read voltage offset profile identifier is specified in an op code transmitted during a last command cycle of the first read command.

7. The apparatus of Claim 1, wherein the read voltage offset profile identifier is specified in an op code transmitted during a first command cycle of the first read command.

8. The apparatus of Claim 1, the controller further to:

receive a configuration command specifying the at least one read offset voltage and the read voltage offset profile identifier; and

store, in a memory, the at least one read offset voltages in association with the read voltage offset profile identifier.

9. The apparatus of Claim 1, further comprising a second controller to select the read voltage offset profile identifier from a plurality of read voltage offset profile identifiers based on an age of data targeted by the read command.

10. The apparatus of Claim 1, wherein the read command is a multiplane read command and the at least one adjusted read voltage is applied to read data from each plane of a plurality of planes specified in the multiplane read command.

11. A method comprising:

receiving a first read command specifying a read voltage offset profile identifier;

identifying a read voltage offset profile associated with the read voltage offset profile identifier, the read voltage offset profile comprising at least one read voltage offset; and

performing a first read operation specified by the first read command using at least one read voltage adjusted according to the at least one read voltage offset of the read voltage offset profile.

12. The method of Claim 11, further comprising specifying the read voltage offset profile identifier in an address cycle of the read command.

13. The method of Claim 11, further comprising specifying the read voltage offset profile identifier in a command cycle of the first read command.

14. The method of Claim 11, further comprising:

receiving a configuration command specifying the at least one read offset voltage and the read voltage offset profile identifier; and

storing, in a memory, the at least one read offset voltages in association with the read voltage offset profile identifier.

15. The method of Claim 11, further comprising selecting the read voltage offset profile identifier from a plurality of read voltage offset profile identifiers based on an age of data targeted by the read command.

16. A system comprising:

a storage device comprising:

a memory device comprising a memory array and a first controller; and a second controller to:

send a configuration command to the first controller, the configuration command specifying at least one read offset voltage and a read voltage offset profile identifier; and

send a read command to the first controller, the read command specifying the read voltage offset profile identifier and an address of the memory array.

17. The system of Claim 16, the second controller to receive data specified by the address of the memory array, the data read by the first controller in accordance with the at least one read offset voltage.

18. The system of Claim 16, wherein the read command specifies the read voltage offset profile identifier in a command cycle or an address cycle of the read command.

19. The system of Claim 16, further comprising a processor to send a read request to the storage device and wherein the second controller is to send the read command in response to receiving the read request

20. The system of Claim 19, further comprising a battery communicatively coupled to the processor, a display communicatively coupled to the processor, or a network interface communicatively coupled to the processor.

21. A system comprising:

means for receiving a first read command specifying a read voltage offset profile identifier;

means for identifying a read voltage offset profile associated with the read voltage offset profile identifier, the read voltage offset profile comprising at least one read voltage offset; and

means for performing a first read operation specified by the first read command using at least one read voltage adjusted according to the at least one read voltage offset of the read voltage offset profile.

22. The system of Claim 21, further comprising means for specifying the read voltage offset profile identifier in an address cycle of the read command.

23. The system of Claim 21, further comprising means for specifying the read voltage offset profile identifier in a command cycle of the first read command.

24. The system of Claim 21, further comprising:

means for receiving a configuration command specifying the at least one read offset voltage and the read voltage offset profile identifier; and

means for storing, in a memory, the at least one read offset voltages in association with the read voltage offset profile identifier.

25. The system of Claim 21, further comprising means for selecting the read voltage offset profile identifier from a plurality of read voltage offset profile identifiers based on an age of data targeted by the read command.
